Description
- This disclosure relates to a system and method for erecting a drilling rig.
- Historically, the main methods for drilling were mechanized with the invention of cable drilling. As technology evolved, drilling developed into more sophisticated processes both onshore and offshore with design features of improved mobility, flexibility and increases in depth of operation.
- While onshore drilling uses the ground as a platform, an offshore environment requires an artificial drilling platform, due to the depth of the ocean floor. At times, it is necessary to move a rig from one location to another. In the past, larger land rigs have been designed to be divided into sections and loads to move to a new place or location. However, these processes are expensive, time consuming, as they often takes weeks to finish.
- With the current trend of innovation in this industry, there have been improvements in the drilling process, such as cost-effective technology, upgraded machine performance and rig mobility. Nevertheless, the following issues remain to be unsolved: expensive machines, such as onsite cranes, difficult assembly, and costs due to down time.
- Hence, it would be useful to have an improved system and method for erecting a drilling rig.
- A system and method for erecting a drilling rig is disclosed herein. A system for erecting a drilling rig can comprise a substructure comprising a base platform. Additionally, the rig can comprise a modular rig mast comprising a plurality of sections, the plurality of sections comprising a first section, and the rig mast mountable to the substructure. Lastly, the rig can comprise a first one or more lifting means, the one or more lifting means each having a first end connected to the rig mast and a second end connected to the structure, the lifting means capable of lifting the rig mast from a horizontal position to a vertical position.
- In addition, a method for erecting a drilling rig is disclosed. A method for erecting a drilling rig can comprise connecting a first section of a rig mast to a substructure using a first locking mechanism, the rig mast in a substantially horizontal position. Additionally, the method can comprise connecting a second section of said rig mast to a first section of the rig mast using a second locking mechanism, to form at least a portion of the rig mast. Additionally, the method can comprise raising the assembled rig mast from the substantially horizontal position to a substantially vertical position, using a lifting means.
- loading a mast platform onto a substructure, connecting a first section a of rig mast onto a substructure by a first locking mechanism, and assembling a plurality of sections of rig mast by a second locking mechanism to form an assembled rig mast. The method further comprises attaching a mast-raising cylinder to a section of a rig mast and raising the assembled rig mast by mast-raising cylinders onto the substructure. Furthermore, the method can comprise a rig mast attaching onto the substructure at the rig mast platform by rig mast legs.

Standingpipe 800 can act as a jack, which can securerig mast 102 at horizontal position. In one embodiment, the horizontal position of assembledrig mast 102 held up by mast-raisingcylinders 601 can be referred to as a structure elevator position 804. Structure elevator position 804 can be sustained for as long as necessary to add appropriate additions to rigmast 102 prior to erectingrig mast 102. -
FIG. 9 illustrates erecting ofrig mast 102. After achieving structure elevator position 804, mast-raisingcylinders 601 can utilize 360-degree rotation capabilities from base ofrig mast 102 and/or top ofsubstructure 103. As a result, mast-raisingcylinders 601 can elevaterig mast 102 from horizontal position to a vertical position. Mast-raisingcylinders 601 can use attachment to upper side of first section ofrig mast 102 a to liftentire rig mast 102. In one embodiment, mast-raisingcylinders 601 can use top ofsubstructure 103 as a pivot point to retract themselves upwards. As a result, mast-raisingcylinders 601 can gradually liftrig mast 102 to vertical position. Therig mast 102 can rotate counter clockwise for roughly 90 degrees, in one embodiment. - In one embodiment, the standing
pipe 800 can aid in pushing up, securing, and/or steadyingrig mast 102. In another embodiment, mast-raisingcylinders 601 can attach at a different point onrig mast 102. Furthermore,cables 307 and/or additional mast-raisingcylinders 601 can be used to erectrig mast 102. -
FIG. 10A illustrates an installedrig mast 102.Installed rig mast 102 can be fully attached tomast platform 200. After mast-raisingcylinders 601 reach an upright position and pullrig mast 102 until completely vertical,rig mast 102 is fully elevated. Oncerig mast 102 is fully elevated, it can be attached tosubstructure 103 attop boxes 201. Particularly, a hook and pin system can be utilized to fasten the upper base legs ofrig mast 102 a totop boxes 201 onmast platform 200. In various embodiments, upper base legs ofrig mast 102 a can be connected totop boxes 201 by a variety of connecting devices and procedures, including, but not limited to, bolting. - At erected rig stage of installation, additional rig parts, such as stairs, houses, pumps, tanks can be attached and installed to
mast platform 200 and/orsubstructure 103 as appropriate at erected rig position, prior to elevation ofmast platform 200. Aside from rig parts accommodating use ofmast platform 200 in the field, other rig parts necessary for drilling can be added as well. Finally, erectedrig mast 102 can be added to and/or further built in accordance with standard procedures of the field and in compliance with code or statute of particular jurisdiction. -
FIG. 10B illustratesmast platform 200 elevating abovesubstructure 103. Atsubstructure 103 beneathmast platform 200,base lifters 104 can raiseentire mast platform 200 andrig mast 102 by lifting at attachments on bottom surface ofmast platform 200.Base lifters 104 can pushrig mast 102 up from underneathmast platform 200. Furthermore, mast-raisingcylinders 601 can remain attached tomast platform 200 to supportrig mast 102 during elevation. -
FIG. 10C illustrates a fully erected land rig. - Various changes in the details of the illustrated operational methods are possible without departing from the scope of the following claims. Some embodiments may combine the activities described herein as being separate steps. Similarly, one or more of the described steps may be omitted, depending upon the specific operational environment the method is being implemented in. It is to be understood that the above description is intended to be illustrative, and not restrictive. For example, the above-described embodiments may be used in combination with each other. Many other embodiments will be apparent to those of skill in the art upon reviewing the above description. The scope of the invention should, therefore, be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. In the appended claims, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein.”
